After seeing the stick on scoop article on the front page, it reminded me of this..

Drag FX - the biggest WTF car accessory that exists.

I've seen this mobile app pop up on the internet a year ago, and it always puzzled me on why it exists. All you need is an OBDII scanner, and an Android or iOS device. an optional stick-on supercharger/blower is the worst.

To answer my curiosity, I watched this video.

Now I might know why. It's for the teenage crowd, who prefer the scream of a supercar or beef of a muscle car, and possibly dislike the brawn of their little four bangers. It's also quite scary that this guy appears to live within 5 minutes of me, I need to keep a lookout for him.
